Javascript is used by programmers around the world to create dynamic and interactive web content such as applications and browsers. JavaScript is extremely popular and the most used programming language in the world, used as the client-side programming language by 97.0% of all websites.
Advantages of choosing JavaScript for mobile app development
1. Speed
Because JavaScript is an "interpreted" language, it takes less time to compile other programming languages such as Java. JavaScript is also a client-side script that speeds up program execution as it saves time connecting to the server.
2. Simplicity
JavaScript is easy to understand and easy to learn. The structure is simple for both users and developers. It is also very easy to implement and saves developers a lot of money in developing dynamic content for their web.
3. Popularity
All modern browsers support JavaScript, so it's almost everywhere. Google, Amazon, PayPal, and other well-known companies all use JavaScript as their tool.
4. Interoperability
JavaScript works perfectly with other programming languages and is therefore preferred by many developers when developing many applications. It can be embedded in any web page or script in any other programming language.
5. Server Load
JavaScript works on the client side, so data validation can be done in the browser itself rather than being sent to the server. There is no need to reload the entire website when there are deviations. The browser only updates selected segments of the page.
6. Extended Interfaces
JavaScript provides developers with a variety of interfaces for creating attractive websites. A drag-and-drop component or slider can provide a rich user interface to your web page. This improves user interactivity on your website.
7. Advanced Features Third-party add-ons like
Grease monkey (Mozilla Firefox extension) allows developers to add predefined code snippets to their code to save time and money. These add-ons help developers create JavaScript applications much faster and easier than other programming languages.
8. Versatility
JavaScript is suitable for both front-end and back-end development. We use NodeJS for backend development, but many libraries such as AngularJS, ReactJS, etc. help us with frontend development.
9. Reduce Overhead
JavaScript improves the performance of websites and web applications by reducing the length of code. Less code overhead by using various built-in functions for loops, DOM access, etc.
The most prominent skills of a JavaScript developer to keep in mind before hiring.
Mastering Data Structures
To write efficient code, developers must be familiar with algorithms and data structures. Unless you're a technical recruiter, you need to understand the data structure.
Simply put, it is used to store and organize data for easy access and manipulation.
Solving a problem is one thing. But solving with efficiency in mind is a whole other level. Different data structures have different tradeoffs in terms of temporal and spatial complexity. Developers should be aware of the most common data structures and their use cases. This allows you to choose the best data structure for your particular problem.
Understanding the DOM
JavaScript developers should be familiar with the Document Object Model (DOM). DOM is basically a representation of the HTML elements on a web page.
When hiring a developer dedicated to web development, ask about the DOM.
It is important for developers to be able to manipulate the DOM so that they can create dynamic web pages. Tests that developers know how to switch classes, manipulate HTML structure, and update styles.
Asynchronous Programming
Asynchronous programming is a technique that allows you to execute code without blocking the main thread. This means that your code can continue to run even if the asynchronous task has not been completed yet.
When working with a development team, asynchronous programming can make a big difference to the overall performance of your application.
Asynchronous programming is essential to building applications. It's also a difficult concept to grasp, so it's important to hire developers who understand it well.
Experience with Node.js
Node.js is a runtime environment that enables developers to create server-side applications in JavaScript. Due to its popularity over the last few years, aspiring JavaScript developers should have some experience.
Node.js is designed to build scalable network applications, so it's a good idea to ask potential developers about large projects they've worked on in the past. An even better idea is to take practice tests to assess your skills. Learn more about the Node.js online tests you can take to narrow down the best developers.
Object Oriented Programming
JavaScript is an object-oriented programming language. That is, the code is organized around objects rather than functions. OOP makes your code more modular and easier to maintain. We recommend hiring a developer who understands OOP concepts well.
Developers should be familiar with the various design patterns used in object-oriented programming.
OOP facilitates code reuse, including already defined classes. Understanding OOP saves developer time. If you have time, you can work on more projects. This means more money for the company in the long run.
Familiarize with HTML and CSS
Although the focus of this article is JavaScript, it's important to remember that languages don't exist in isolation. A good JavaScript developer should also have a solid foundation in HTML and CSS.
HTML requires familiarity with the various elements and their semantic usage. This is useful when you need to create dynamic video content that is responsive and accessible. With CSS, you should know how to write clean and maintainable code that can scale as needed.
A good understanding of HTML and CSS is also helpful when debugging code. If there is a problem with the display, a good developer can track it down
Conclusion.
That's all! These are all the most important skills every JavaScript developer should have to get hired easily. Learn all about it or consult an expert for a better understanding. But don't skip a single skill set. As you can see, all skills are important.
